HD 5670 fps problems with 2 games

[Inkcat]

So, I recently took the Tom's Hardware advice for best value card for the June edition and picked up a Sapphire 5670 HD 1gigGDDR5 version.

I'm loving the card's performance in my machine so far, but I have two weird questions. I'm having massive framerate issues in two games in particular, Rift and League of Legends. The machine runs TF2 and Starcraft 2 even better than it used to, I'm getting a stable 60+ fps in both on medium/high settings.

But after the card, LoL in particular, has just awful framerate problems. Is this a known driver issue? Is it with LoL? There's absolutely nothing wrong with my computer, but the old 4670 I had ran the game stable on high.

I've got a 650W Antec power supply, AMD Phenom XII Black 555, 4gigs of memory, Win7. The issue doesn't seem to be coming from the computer, especially considering it runs more graphic intensive games better.

Basically, what I'm wondering, is there a driver version that's considered "best"? I've done some reading and found that the 11.x drivers have caused issues for a lot of people, but I have no idea what to move to.

It's most likely a driver issue, the best for the 5670, has to be 10.5, try it out, people say it was the last good one because the newer one to it cause laggy framerates in certain games, so give it a try, be sure to delete the old ones!

10.5!!?

Of course I have no idea what resolution your using but is it possible you were playing in dx10 with your 4670 and are now playing the game in dx11 with the new card?

I don't think so, as far as I know, neither TF2, SC2, or LoL are DX11.

Yeah I know, I was skeptical too but everyone says that's the best for the 5670.

Thanks a ton. I'm running the 10.5's now and you were right, everything is running smoothly and nicely, no hiccups.

ATI, what the heck.
